Background: Essential thrombocythemia (ET) is a clonal hemopoietic stem cell myeloproliferative neoplasm characterized by persistent thrombocytosis along with megakaryocytic hyperplasia. In the last decade following the identification of an acquired JAK2 V617F mutation, there has been acceleration in our understanding of this disease. The rational of this study was to determine the mutational profile of JAK2 V617F in Pakistan patients with ET. Materials and Methods: In this retrospective cross sectional study, 21 patients with ET were enrolled from January 2011 to December 2014. Patients were diagnosed based on WHO criteria for essential thrombocythemia. Complete blood count was done on an automated hematology analyzer, while JAK2 V617F expression was evaluated by polymerase chain reaction. Results: The mean age was $56.7{\pm}19.0$ years (range 18-87) and the male to female ratio was 1:1.1. The frequency of JAK2 V617F positivity in our ET patients was found to be 61.9%. The mean hemoglobin was $11.7{\pm}2.4$ g/dl with a total leukocyte count of $13.3{\pm}8.1{\times}109/l$ and a platelet count of $1188{\pm}522{\times}109/l$. Positive correlations for JAK2 V617F mutation were established with high TLC count and raised LDH (P<0.05). No correlation of JAK2 V617F could be established with age and gender (P>0.05). Conclusions: JAK2 V617F mutation frequency in our ET patients was similar to those reported previously. Screening for the mutation in all suspected essential thrombocythemia cases could be beneficial in differentiating patients with reactive and clonal thrombocytosis.

Purpose: We aimed to study the inflammatory parameters of complete blood count in breast cancer cases. Materials and Methods: This retrospective study covered 178 breast cancer patients and 107 age and body mass index matched healthy women. Complete blood count parameters, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and MPV/platelet were analyzed. Results: The leukocyte, neutrophil and neutrophil/lymphocyte ratio were higher in the patient group (p values 0.001, 0.0001 and 0.0001, respectively) while haemoglobin and hematocrit were higher in the control group (p=0.0001 for both). Logistic regression analysis showed that elevated neutrophils and platelet distribution width (PDW) (OR: 0.627, 95%CI: 0.508-0.774, p=0.001 and OR: 1.191 95%CI: 1.057-1.342 p=0.003) were independent variables for predicting breast cancer. The cut-off value for the neutrophil/lymphocyte ratio was 2.56. Conclusions: According to our study results, neutrophil levels as part of complete blood count may be used as an independent predictor of breast cancer risk.

The purpose of this study was to determine the effects of heat application on the immune activities of the human body. To exam, furthermore, the immune effect from the healthy volunteer(male:15, female:15) by monitoring changes of immune substances such as various leukocytes[total white blood cell(WBC), eosinophil, neutrophil, basophil, monocyte, and lymphocyte], a comparative study with warm water immersion($40.8{\pm}0.3^{\circ}C$) and infrared(250W) was carried out. The plasma analysis showed that the count of white blood cell, eosinophil, and neutrophil were elevated in warm water immersion- or infrared. stimulated group compared with control group. However, the count of basophil was decreased in both warm water immersion- and infrared-stimulated group than control group. Therefore, these results suggest that the thermostimulation improved immune activity.

In recent, many cardiac centers have preferred off-pump coronary artery bypass grafting (CABG) to on-pump CABG to prevent the adverse effects of cardiopulmonary bypass. The present study was performed to prove beneficial effects of off-pump CABG. Sixty adult patients scheduled for elective CABG were randomly assigned to On-pump group (n=30) or Off-pump group (n=30). Arterial blood samples were drawn before and after the operation (Pre-OP and Post-OP, respectively) for measuring CBC, prothrombin time, activated thromboplastine time, blood gas analysis, creatine kinase-MB (CK-MB) level, and lactate dehydrogenase (LDH) level. Perioperative parameters including heparin and protamine usages, complications, blood components usages, blood loss, ventilation and ICU-staying time, and hospitalization were also evaluated. Platelet count at Post-OP was high in Off-pump group whereas CK-MB and LDH levels were low compared with On-pump group. Off-pump group had significantly lower heparin and protamine usages, lower total leukocyte count, higher hematocrit and hemoglobin levels, less blood loss, lower usages of blood components, shorter ventilation and ICU-staying time, and lower incidence of pleural effusion than On-pump group. Other variables did not significantly differ between two groups. These results showed that Off-pump CABG was a satisfactory technique with less inflammatory reaction, less cardiac damage, less postoperative complications, and less cost.

Although considerable research has been done on the blood picture of the horse, hot-blooded and cold-blooded, little work has been made of the blood picture of the army pack horse, Jeju horse. The object of the present investigation was to make good this deficiency, and to suggest standard for the blood picture of army pack horses kept under the regular military training and the ideal feeding in the heart of a mountain. Blood samples were drawn from the jugular vein through a 15-gauge bleeding needle from 41 males and 28 females, aging 3 to 9 years old. It was taken between seven and nine o'clock in the morning. Animals were handled as quietly as possible to avoid any excitation. No restraint other than a halter was used. Enumeration of erythrocyte, total and differential leukocyte count, determination of hemoglobin in blood, and the value of packed cell volume were male in the usual manner, and erythrocytic constant was calculated by the method of Wintrobe. Erythrocyte count was $7.83{\pm}0.20(4.95{\sim}11.05){\times}10^6/mm^3$(SE). This value was much lower than hot-horses, but slightly higer than the values of cold-horse reported from foreign country. Concentration of hemoglobin in blood was $13.0{\pm}0.33(9.5{\sim}17.8)g/100ml$. This value was much higher than that of cold-horses observed by the other authors, approaching to the values of hot-horses. Packed cell volume was $32.1{\pm}0.92(22{\sim}42)ml/100ml$. This vague was a little higher than that of the other cold-horses. Mean corpuscular volume was $41.5{\pm}1.20(26.6{\sim}59.3){\mu}m^3$. This value matched so well with the other results recorded by various investigators. Mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were $16.9{\pm}0.43(12.3{\sim}25)$ pg and $41.0{\pm}0.45(29.1{\sim}51.1)g/100ml$, respectively. These values were significantly higher than the values found by the other investigations. Total leukocyte enumeration was $10.5{\pm}0.41(5.6{\sim}17.9){\times}10^3/mm^3$, being considered as normal. And differential leukocyte count of neutrophil was $44.5{\pm}2.23(15{\sim}76)%$, $5,527{\pm}234(2,231{\sim}9,144)/mm^3$, of lymphocyte $50.5{\pm}1.19(19{\sim}77)%$, $4,307{\pm}125(1,456{\sim}11,098)/mm^3$, of monocytel (0~4)%, $105(0{\sim}352)/mm^3$, of eosiophil 3.2(0~14)%, $340(0{\sim}1,232)/mm^3$ and of basophil 0.25(0~3)%, $23(0{\sim}236)/mm^3$. The percentage of the differential count obtained from the present work showed a good agreement with the results of various authors. Of the horses examined monocyte was found from 42 horses, eosinophil from 62 horses and basophil from 10 horses. No significant differences recognized between male and female horses, and the effect of age was not observed between three to nine years old. Judging from the blood picture of the present investigation, it could be stated that the army pack horses on training were kept better than the average farming conditions.

To determine the efficiency of copper (Cu) supplementation, a feeding experiment was carried out with 240 day old broiler chicks (vencobb-100). Birds were divided into four dietary treatments: i) C - no additives, ii) $T_1$-75 mg inclusion of Cu/kg diet, iii) $T_2$-150 mg inclusion of Cu/kg diet, iv) $T_3$-250 mg inclusion of Cu/kg diet. The present study was carried out in the Department of Animal Physiology, West Bengal University of Animal and Fishery Sciences, Kolkata, India for a period of 42 days (6 weeks). Growth performance was measured in terms of live weight gain, cumulative feed intake and feed conversion ratio at the end of $21^{st}$ and $42^{nd}$ day of the experiment and the result was found to be encouraging for commercial enterprises when the chickens were fed at 150 mg Cu/kg ($T_2$) of their diet. Excess dietary copper more than 150 mg/kg reduced the haemoglobin (Hb) concentration in blood and resulted in the accumulation of copper in the liver with decreased blood Hb concentration and packed cell volumes (PCV). Copper supplementation increased the total erythrocyte count (TEC) as copper is involved in erythropoiesis. But, from the result it is indicated that the dietary copper concentration could not alter the total leukocyte count (TLC). In case of different leucocytes count (DLC), there were no significant differences observed among the different treated groups. Statistical analysis showed significant (p<0.01) difference in plasma concentration of copper, zinc, ferrous and cholesterol among the different copper treated groups. The result indicates that supplementation of copper is an effective way of improving the production performance and haematological parameters in broiler chicken.

Safety of recombinant porcine somatotropin administration on pig was studied using 32 Landrace x Yorkshire crossbred pigs. The starting body weight ranged from 55.5kg to 65.3kg. Eight pigs were allotted to each low dose group of sustained releasing rPST(SL), high dose group of sustained releasing rPST(SH), daily injection group of rPST(DI), and control group(C). Pigs in SL group and SH group were injected subcutaneously twice in 3 week-interval with 1000$\mu\textrm{g}$ and 2000$\mu\textrm{g}$ of sustained releasing rPST per kg body weight, respectively. Pigs in DI group were injected intramuscularly with 100$\mu\textrm{g}$ of rPST everyday for 6 weeks. Blood was collected from anterior vena cava just before the first treatment, and at four weeks and six weeks of experiment. Hematological parameters and blood chemical parameters indicating liver function, kidney function, electrolyte metabolism, mineral metabolism and lipid metabolism were determined. Necropsy and urinalysis were performed after final blood collection. The results were summarized as follows, and it is concluded that rPST administration does not affect pig health negatively. 1. rPST administration did not affect kidney function as manisfested by BUN, creatinine and urinalysis. 2. rPST administration did not affect liver function as manisfested by total protein, albumin, serum AST activity serum ALT activity serum ALP activity, serum LDH activity, serum GGT activity and serum SDH activity. 3. rPST administration did not affect skeletal muscle, cardiac muscle and brain as manifasted by serum AST activity and serum LDH activity. 4. rPST administration increased blood glucose level within normal range. 5. rPST administration did not affect lipid metabolism as manisfested by triglyceride, cholesterol, and phospholipid concentrati on. 6. rPst administration dia not affect mineral metabolism as manisfested by calcium, phosphorus, magnesium and iron concentration. 7. rPST administration did not affect electrolyte metabolism as manisfested by Na, K, chloride concentration. 8. rPST administration did not affect erythrocyte count, leukocyte count, thrombocyte count, and plasma fibrinogen level.

Background: Polycythemia rubra vera (PV), being a primary polycythemia, is caused by neoplastic proliferation of erythroid, megakaryocytic and granulocytic lineages which result in panmyelosis. PV patients have a somatic acquired mutation in the Janus kinase (JAK2) pathway, rendering cell proliferation independent of the normal regulatory mechanisms that regulate erythropoiesis. The rational of this study was to determine the prevalence of the JAK-2 V617F mutation in Pakistani patients with PV. Materials and Methods: In this cross sectional study, 26 patients with PV were enrolled from January 2010 to December 2014. Patients were diagnosed based on WHO criteria for PV. All were screened for G-T point mutation (V617F) in the JAK2 gene on chromosome 9 by an allele specific PCR. Results: The mean age was $53.4{\pm}9.31years$ (range 36-72) and the male to female ratio was 2:1. The frequency of JAK2 V617F positivity in our PV patients was found to be 92.3%. Overall 30.7% of patients were asymptomatic and remaining 69.3% presented with symptomatic disease. The mean hemoglobin was $18.1{\pm}1.9g/dl$ with the mean hematocrit of $55.6{\pm}8.3%$. The mean total leukocyte count was $12.8{\pm}7.1{\times}10^9/l$ and the platelet count was $511{\pm}341.9{\times}10^9/l$. A positive correlation of JAK2 V617F mutation was established with high TLC count (P=0.01). No correlation of JAK2 V617F could be established with age or gender (P>0.05). Conclusions: The JAK2 V617F mutation frequency in our PV patients was similar to those reported internationally. Screening for the mutation in all suspected PV cases could be beneficial in differentiating patients with reactive and clonal erythrocytosis.

Background: Essential thrombocythemia (ET) is a Philadelphia chromosome-negative myeloproliferative neoplasm characterized by sustained thrombocytosis and megakaryocytic hyperplasia. It is an uncommon hematological malignancy which primarily affects elderly individuals. The rational of this study was to determine its clinico-hematological profile along with risk stratification in Pakistan patients. Materials and Methods: In this retrospective cross sectional study, 21 patients with ET were enrolled from January 2011 to December 2014. Data was analyzed with SPSS version 21. Results: The mean age was $56.7{\pm}19.0years$ (range 18-87) and the male to female ratio was 1:1.1. Of the total, 62% of patients were above 50 years of age. Overall 61.9% were diagnosed incidentally and were asymptomatic. In symptomatic patients, major complaints were weakness (19%); erythromelalgia (14.2%), transit ischemic attack (9.5%) and gastrointestinal bleed (4.7%). The mean hemoglobin count was $11.7{\pm}2.4g/dl$ with a total leukocyte count of $13.3{\pm}8.1{\times}10^9/l$ and platelets count of $1188.8{\pm}522.2{\times}10^9/l$. Serum lactate dehydrogenase, serum creatinine and uric acid were $454.3{\pm}127.8$, $1.2{\pm}0.5$ and $7.4{\pm}3.4$ respectively. According to risk stratification, 57.1% were in high risk; 23.8% in intermediate risk while 19.1% in low risk group. Conclusions: ET in our patients in Pakistan, unlike in the West, is seen in a relatively young population. Primarily patients were asymptomatic and risk stratification revealed predominance of high risk disease in our setting.

Delayed arrival of blood samples from the field and a large number of samples delivered often causes delay in sample analysis leading to inaccurate measurements. Therefore, this study aimed to assess whether prolonged storage in refrigerator could influence the stability of cattle blood samples and to establish an optimal time limit for complete blood count (CBC) parameters and blood gas and electrolyte (BGE) parameters analyses. Samples collected from healthy cows were tested immediately for CBC and BGE using automated hematology, blood gas and electrolyte analyzers. Samples were kept in refrigerator at 4℃ and analyzed after 6 h, 12 h, 24 h, 48 h, 72 h, 120 h, and 192 h of storage. Mean differences between observations were assessed at 5% significance level using ANOVA and Duncan's multiple range test. Total CBC parameters and the platelet profile remained stable for 192 h, except for MCHC. Among leukocyte-related counts, NEU and EOS remained stable for 192 hours. WBC and LYM, and MONO values produced inconsistent measurements which recovered its initial measurement after 12 h and 24 h of storage, respectively, then remained stable until 120 h. Among the blood gas indices, PCO₂, PO₂, tCO₂, and BE showed declining and significant changes over time, but pH, tHb, and SO₂ remained stable for 192 h. Electrolyte status in the blood showed that ions are unstable and tend to change in as early as 6 h of storage. This study established that cattle blood specimens for CBC analysis can be stored for 120 h at 4℃, but specimens for BGE analyses must be tested within 6 to 24 h.
